Abstract: Realizing the practical efficacy of the institutional strengths of the new system for mobilizing resources nationwide for the high-quality development of competitive sport requires, first and foremost, a theoretical reckoning with their endogenous relationship and with the systemic logic that enables this institutional apparatus to drive fundamental transformation within the domain of competitive sport. This study posits that the new system for mobilizing resources nationwide and the high-quality development of competitive sport are not merely functionally aligned but deeply embedded in each other across the trajectory of institutional change and the ongoing practice of sports development, such that they stand in a relation of reciprocal empowerment: the former constitutes the institutional cornerstone, while the latter furnishes the vital practical terrain on which the former's epochal superiority is rendered visible and effective. The intrinsic logic through which the new system for mobilizing resources nationwide enables the high-quality development of competitive sport can be articulated along three interrelated dimensions. 1) It drives the optimization and upgrading of organizational structures through institutional reconfiguration of cross-sectoral collaboration, an expansion of coordination boundaries, and a strategic redefinition of functional mandates. 2) The system draws on the complementarity between a capable state and a well-functioning market to forge an open, reciprocal resource-dependence architecture, which in turn supports value-added resource management and significantly enhances allocative efficiency across competitive sport. 3) With breakthroughs in core and critical technologies as its strategic fulcrum, it advances the integrated deployment of frontier technologies in competitive sport, coupled with the independent development of advanced sports science and technology, together generating a systemic leap in the sector's innovation capacity. To realize the sports powerhouse vision by 2035, the high-quality development of competitive sport must be driven by a tripartite strategic framework: a purpose-built new system for mobilizing resources nationwide for competitive sport serving as its pivotal instrument; a systematic national strategic scientific and technological force in sport providing its underlying momentum; and a governance mechanism that fuses state leadership with market forces. Through this integrated architecture, the development of competitive sport will be progressively aligned with the evolving socialist market economy, articulated with the prevailing international sporting landscape, and calibrated to the sporting needs of the populace.
